GEORGE H. VILLIAMSON, OF SKANEATELES, NEV YORK, ASSIGNOR OF ONE- HALF TOSTEPHEN THORNTON, OF SAME PLACE.

AXLE FOR HARVESTER-TRUCKS.

SPECIFICATION forming'partof Letters Patent No. 424,398, dated March 25,1890. Application filed September 6, 1889. Serial No. 323,135.(Normodel.)

To @ZZ whom it may concern: Be it known that I, GEORGE H. VILLIAM- SON,a citizen of the United States, residing at Skaneateles,in the county ofOnondaga, State of New York, have invented certain new and usefulImprovements in Harvester-Castings, of which the following is aspecification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in trucksdesigned, primarily, for use in moving reapers and binding-machines,although, of course, it is applicable to other uses.

The novelty resides in the peculiarities of construction and thecombinations, arrangement, and adaptation of parts, all as more fullyhereinafter` described, shown in the drawings, and then particularlypointed out in the appended claims.

The invention is clearly illustrated in the accompanying drawings,which, with the letters of reference marked thereon, form a part of thisspecification, and' in which- Figure l is a side view of the frontbearing with the axle in place. Fig. 2 is a central longitudinalvertical section of the rear bearing with the axle in place. Fig. 3 is afront view of the front bearing with the axle removed. Fig. 1i is avertical section on the line oc of Fig. 3. Fig. 5 is a vertical. sectionon the line y y of Fig. 3. Fig. 6 is a front view of the rear bearingwith the axle removed.

Like letters of reference indicate like parts throughout the severalviews.

Referring to the details of the drawings by letter, A designates acasting formed with extension A', the upper face of which is curved orconcaved, as shown, to conform to the shape of the tubular portion B ofthe frame, and with a substantially Z-shaped portion or iange A2,designed to be secured to the portion B of the frame by means ofsuitable bolts B2. This casting is also formed with an internal screw-45 threaded portion A3, from which 'projects a ledge or rib A4, theopposite end of said screwthreaded opening being polygonal in shape, asshown at A5, to receive a correspondinglyshaped shoulder on the axle, ashereinafter 5o described.

B3 is a bolt passed through the tubular por- C is a pipe or tube securedin the casting 6o A by means of screw-threads engaging the threadedportion A3 thereof.

D is a casting in many respects similar to the casting A, and is formedwith a` concave portion D to receive the tubular portion E of the trameand secured by means of the bolts D2. This casting has a screw-threadedportion having at one end a polygonal porltion to receive acorrespondingly-shaped shoulder on the axle.

F is a tube or pipe screw-threaded at its ends and engaging the interiorscrew-threads of the casting D, there being of course two castings D andtwo castings A, one at each end of the tubes C and F.

G are the axles formed with tubular shanks G', which it within the tubesC and F, and are formed, preferably, with a polygonal shoulder G2, whichfits the correspondingly-shaped socket in the castings and abuts againstthe 8o end of the tube, as shown clearly in Fig. 2, to prevent turningof the axle therein. The axles are otherwise formed in the ordinarymanner with skein and screw-threaded end for the reception of a nut, asshown in Fig. 2.

The axles are secured in the tubes iirmly with the polygonal portions inthe correspondingly-shaped socket by means of Wedgeshaped keys H, whichpass through a suitably-shaped opening in the tubes and in thecylindrical 9o shank of the axle.

In order to aid in the removal of the axle from t-he tube when desired,in case it should bind therein, I have in the-tube a slot H', preferablyat right angles to the slot or opening, through which the key passes, soas not to weaken the same, through which the key may be inserted afterits removal from the slot, in which it is shown in Fig. 2, for thepurpose of driving the axle out, the key acting like a 1o@ wedge againstthe inner end of the shank of the axle, forcing it out.

Various modifications may be resorted to Without departing from thespirit of my invention. For instance, the shank ofthe axle may be squareor polygonal to t a correspondingly shaped tube or socket; or the shankof the axle may be secured in the tube or socket by means of a boltpassing` through the same; or the tube or socket may be short or in twopieces, the essence of the invention residing in the movable axleirrespective of its manner of attachment.

The tube in which the axle-arm is inserted may sometimes b e a part ofthe frame used on all machines, thereby saving an extra iron and also asaving of labor. It will of course be understood that the castings willbe formed so as to fit differentlmachines.

1. The combination, with the casting and the tube held therein, of theaxle having a shank fitted to said tube and formed with polygonalshoulder engaging a corresponding socket in the casting, substantiallyas described.

. 2. The combination, with the casting formed with concave portion toreceive a portion of the frame, of a tube held in said casting and anaxle having a shank secured in said tube, substantially as described.

3. The combination, with the casting having concaved portion to receivea portion of the frame and a screw-threaded portion with polygonalsocket, of a tube engaging said screw-threaded portion, and an axlehaving a shank fitted in a tube and a polygonal shoulder engaging saidsocket, substantially as shown and described.

4. The combination, with the casting having concave portion to receive aportion of' the frame and screw-threaded portion with polygonal socket,of a tube having a screwthreaded portion engaging the threaded portionot the casting, an axle having a shank fitting said tube and polygonalportion fitting said socket, and a wedge-shaped key passed through thetube and shank, substantially as described.

A5. The combination, with the casting having a concave portion toreceive a portion of the frame and screw-threaded portion with polygonalsocket, ot' a tube having a screwthreaded portion engaging the threadedportion of' the casting, an axle having a shank fitting said tube andpolygonal portion fitting said socket, and a wedge-shaped key passedthrough the tube and shank, said tube having a slot H to the rear of theshank, substantially as described.

v6. The combination, with the casting having concave portion to receivea portion of the frame and a screw-threaded port-ion with polygonalsocket, ot a tube having a screwthreaded portion en gagingthe threadedportion ot' the casting, an axle having a shank fitting said tube andpolygonal portion fitting said socket, and a wedge-shaped key passedthrough the tube and shank, said tube having a slot II to the rear ofthe shank, said slot arranged at right angles to the one through whichthe key passes, substantially as described.

7. A castingforthe purpose described formed with concave extensions andthreaded portion with polygonal sockets and a substan` tially Z-shapedflange, substantially as shown and described.

In testimony whereof I affix my signature in presence of two Witnesses.

GEORGE H. WILLIAMSON.
